Replacing questionable Samwha HV caps for Rubycon in a HF Amp

So I have a perfectly good working OM Power 4001A HF amplifier. Its very nicely made with the possible exception of the HV filter caps, which are Samwha HC series 450v 330uf parts. I know Samwha has a very questionable reputation for quality and certainly not on par as Rubycon. So I am contemplating replacing the Samwha caps with some Rubycon HXH series which on paper appear to be vastly superior with ripple current capacity and longevity.
Here is a link to the OEM Samwha's;

And the proposed Rubycon's;

Anyone have issues with Samwha caps?
Edit, adding the datasheets.
